Detailed explanation-1: -Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter.

Detailed explanation-2: -The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture.

Detailed explanation-3: -So, we can see that clay soil is a mixture of mainly clay particles, some silt particles, and a small amount of humus and sand particles.

Detailed explanation-4: -Black soil contains fine clay particles and is very useful wherever rainfall is less because it is able to .

Detailed explanation-5: -The largest, coarsest mineral particles are sand. These particles are 2.00 to 0.05 mm in diameter and feel gritty when rubbed between your fingers. Silt particles are 0.05 to 0.002 mm and feel similar to flour when dry. Clay particles are extremely fine-smaller than 0.002 mm.
